Some Comments before I begin to show OC results :
Board layout, packaging and accessories:
The board is a full ATX board, not mATX which is misleading when it was launched
Board comes with LED error debugger, when in Windows it actually displays the CPU die temperature
Comes with on board Power, Reset and reset CMOS buttons which is really a plus for this level board
The clearance between the RAM slots and the CPU socket is far enough that a TRUE with a fan between the socket and slots will not cause interference with RAM sticks that have high HS fins....this seems to be a problem with most X58 boards I've tried.
Only thing that I do not like about the board layout is the 8 pin CPU power socket somewhat oddly situated to the left of the PWM HS which means you have the cable running across the PWM HS, normally the socket is just behind the PS2 socket out of the way.
Only drawback I see on the design is the fact that it only comes with one x 16 PCIe slot, it has 4 x PCIe slots which are as follows, from the socket side : x 16, x 8, x4 , x4. This will hamper any SLI or Crossfire configuration with higher end cards such as GTX 280 or HD 4890 repectively.
In general I'm very pleased with the board's layout, not crowded, well thought through.
Bios :
Most of the X58 board's Bios are so loaded with features that it is confusing even for the people that have had a few boards.
This EVGA X58 LE Bios IMO have got it right with the balance of functionality and practicality...you have enough settings to optimize your OC, at the same time they did not overload you with all sorts of settings that makes it challenging to use.
Under CPU features you will notice all the relevant EIST and C1E and other settings one disables in preparation for OC has already been disabled, even when you start after clear CMOS, very nice of EVGA to do that IMO.
Enabling Turbo mode is also automatic, I have found that on some X58 boards out there it is quite a mission to figure out how to enable turbo, with this board is is ready to go.
Under PC health all the relevant voltages and temperatures are displayed, some boards out there still do not show this in the bios
Your target CPU speed based on what you set your base clocks (i.e. Host Frequency) is displayed so no guessing
All the voltage settings are set in a list except for CPU VTT which is a +number, not sure why, the Biostar board's bios normally likes these +number for their voltage settings, personally I do not as you then have to note the default voltages and add on whetever you set it in the bios.
True to EVGA you can set the RAM speeds on a multiplier based on CPU's base clock speed or you can set it unlinked (i.e. 800, 1073, 1333, 1600 etc) which I have always liked and glad they put this feature on their X58 board.
You can as with most boards set your uncore frequency to be linked (auto) which sets it to 2 x RAM speed or you can set it by using the drop down list.
At the bottom of ypur main OC menu you can save and load your OC profile, nice to save a stable one and work from there, if it fails then you just reload the stable one.
